Decades later, that reputation remains largely intact.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Most transmission problems encountered today are age-related rather than design-related. Worn seals, old fluid, tired clutches and neglected maintenance account for the majority of failures.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The good news is that parts remain widely available, specialist knowledge is abundant, and many problems can be prevented through regular servicing and sensible upgrades.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Whether your Holden runs a Trimatic, Turbo 400 or manual gearbox, investing in preventative maintenance is far cheaper than dealing with a complete transmission rebuild.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Related Articles<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/australianholden.com\/index.php\/2026\/06\/17\/trimatic-common-issues-explained\/\" type=\"post\" id=\"7314\">Trimatic Common Issues Explained<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/australianholden.com\/index.php\/2026\/06\/20\/powerglide-trimatic-issues-explained\/\" type=\"post\" id=\"7309\">Powerglide &amp; Trimatic Issues Explained<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/australianholden.com\/index.php\/2026\/06\/17\/hq-hj-hx-hz-and-wb-holden-cooling-system-problems\/\" type=\"post\" id=\"7320\">HQ HJ HX HZ WB Holden Cooling System Problems<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/australianholden.com\/index.php\/2026\/06\/20\/holden-202-engine-issues-explained\/\" type=\"post\" id=\"7311\">Holden 202 Engine Issues Explained<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/australianholden.com\/index.php\/2026\/06\/17\/hq-hj-hx-hz-and-wb-holden-electrical-problems\/\" type=\"post\" id=\"7332\">HQ HJ HX HZ WB Holden Electrical Problems<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/australianholden.com\/index.php\/2026\/06\/17\/how-to-inspect-a-hq-hj-hx-hz-or-wb-holden-before-buying\/\" type=\"post\" id=\"7318\">How to Inspect a HQ HJ HX HZ WB Holden Before Buying<\/a><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The HQ, HJ, HX, HZ and WB Holden range earned a reputation for being tough, dependable and easy to maintain.
